DISH-CLEAN ER.

SPECIFICATION forming part `of Letters Patent No. 556,358, dated March17, 1896.

Application filed March 26, 1895. Serial No. 543,252. (No model.)

To all whom it 11mg/ concern:

Be it known that I, WILLIAM C. MAXFIELD, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented anew and useful Dish-lVasher, of which the following is aspeciiication.

This invention aims to provide a machine for washing dishes which willcreate a current of water through the dish-receptacle when the latter isrotated, thereby facilitating the process of dish-washing and insuring athorough cleansing of the dishes.

The improvement consists of the novel features which hereinafter will bemore fully set forth and claimed, and which are shown in theaccompanying drawings, in which- Figure l is a central vertical sectionof a dish-washing machine embodying the essence of the presentinvention. Fig. 2 is a sectional View similar to Fig. l, taken at rightangles thereto, showing the dish -receptacle suspended within theboiler. Fig. 3 is a bottom perspective View of the dish-receptacle, theupper portion of the crank being broken away. Fig. 4 is a detail viewshowing the form of a swinging bail,the latter being turned over theedge of the boiler. Fig. 5 is a detail view of a modification.

The boiler l may be of suitable shape and size, being preferablycylindrical in form and constructed of sheet metal, such as block-tin orgalvanized sheet-iron, and is provided centrally of its bottom with avertical journal 2 upon which the dish-receptacle 3 is free to rotate,the latter having a bearing 12 to receive the journal 2. Handles 4 areprovided on the sides of the boiler for convenience of handling thelatter, and swinging bails 5 are located at diametrically-oppositepoints, and,

are adapted to swing over the upper edge of the boiler to be engaged byhooks 6 on the sides of the dish-receptacle, whereby the latter issuspended when it is required to drain the water from the dishes orcomplete the cleansing process by pouring scalding water over the disheswhile the latter are held in the said receptacle. These swinging bails 5are formed from stout wire and have pivotal connection with the sides ofthe boiler, so as to be turned over the upper edge of the latter whenrequired to support the dish-receptacle. Vhen not in use the bails 5 areturned out of the way, as shown most clearly in Fig. l.

The hooks 6 are broad, and the inner or supporting ends of the bailshave a corresponding length, so as to centralize the receptacle andprevent tipping of the latter when held in suspension within the boiler.

The hooks 6 project a short distance from the sides of thedish-receptacle and do not touch the walls of the boiler, therebyoffering no resistance to the free rotation of the dishreceptacle whenthe latter is performing the function for which the machine is designed.

The dish-receptacle 3 is cylindrical in form and closed at its lowerend, the upper end being open to receive the dishes and admitting of thesame being piled therein. Slots or oblong openings 7 are formed in thesides and bottom of the receptacle. 3, the slots in its sides extendingvertically and those in the bottom in radial lines. Hoods or deflectors8 close the slots or openings '7 on three sides and flare outwardly fromthe closed to the open side of the said slots 7. The open sides of thehoods or deflectors provided on the sides of the dish-receptacle extendin the same direction, and the same is true of the hoods or defiectorsprovided on the lower side of the receptacle-bottom, but the hoods ordeiiectors on the sides of the receptacle open in an opposite directionto the hoods or deflectors arranged on the bottom of the receptacle, fora purpose which will presently be made apparent. These hoods ordetlectors 8 are strips of sheet metal which have triangular-shapedflanges at their ends, and which are secured to the receptacle by solderor other means, so that the strips incline in cross-section away fromthe side of the receptacle ,to which one edge is attached.

A yoke 9 is attached at its ends to diametrically-opposite points of thereceptacle 3, and is provided with a crank l() midway of its ends, bymeans of which the receptacle is rotated within the boiler. This crankl0 operates through an opening in a conical-shaped cover 1l, by means ofwhich the boiler l is closed. l/Vhen the receptacle is in place it issupported upon the vertical journal 2, and is steadied by means of thecrank l0 obtaining IOO a bearing in the opening of the cover 1l, as willbe readily understood.

The dishes to be cleansed are piled within the receptacle 3 in anyconvenient manner, and the latter is placed within the boiler l, thecentral depression in its bottoin being fitted upon the vertical journalf3, the water for effecting the washing having previously been suppliedto the boiler, or it may be sup plied thereto after the receptacle isplaced in position and should be of proper temperature to effect thedesired result. The machine being in readiness for operation, the coverl1 is placed in position and the receptacle 3 is rotated by means of thecrank l0 in the desired direction. If the receptacle travels in thedirection corresponding to the open sides of the hoods or deflectors onthe sides of the said receptacle, the waterwill be caught up bythe sidehoods or deflectors and forced into the receptacle, and will escapethrough the openings in the lower side of the receptacle-bottom, therebycausing a forced current through the said receptacle from the sides intothe receptacle, and from the latter out through its bottoni; but if therecepiacle is rotated in an opposite directionthat is, correspondingwith the open sides of the bottom hoods or defleetors-the current willbe in an opposite direction that is, through the bottom of thereceptacle in an upward direction and out through its sides.

It will be observed by a well-established principle that when the hoodsare advanced with their closed sides foremost a suction will be createdat the open sides and cause the water to flow therethrough. Advantage istaken of this principle in the construction and provision of thedetlectors herein set forth, because one set of deflectors catch up thewater and force it into the receptacle, while thc other set by a suckingaction draw the water from the receptacle, thereby creating a stron gcurrent of water through the receptacle, which effects the cleaning ofthe dishes in a comparatively short space of time.

In disposing and providing the hoods or defiectors it is apparent thatchanges in the form, proportion, and the ininor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Then desired the swinging bails may be attached directly to the sides ofthe dish-receptacle in such a manner as to swing outward and engage withthe upper edge of the boiler and sustain the dish-receptacle in anelevated position therein when draining and drying the dishes after thecleansing process. This is most clearly shown in Fig. 5 by the numeral5.

Having thus described the invention, what is claimed as new is- Thecombination with a boiler, of a dishreceptacle rotatably mounted in theboiler and having approximately radial slots in its bottom and verticalslots in its sides, said slots being comparatively long and narrow,hoods or deflectors applied to the bottom of the dislireceptacle andcovering the radial slots at one side and at their ends, said hoodshaving their open sides facing in the same direction, and hoods ordeflectors of corresponding shape to those fitted to the bottom of thedish-1e ceptacle secured to the sides thereof and coverin g the verticalslots formed therein at their ends and one side, the vertical hoodshaving their open sides facing in the saine direction, which isdiametrically opposite to the bottom or horizontal hoods, substantiallyas set forth for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
